fli:pointer-address

(fli:pointer-address pointer)

The address a foreign pointer holds, as an integer -- what an ffi: function takes for a pointer. Part of the macOS-only fli package, beside objc -- the interpreter (java -jar, or the rontolisp native binary), a compiled .class / .jar and a --native executable for macOS on Apple silicon, never a .wasm. See the macOS GUI guide.
